Zek (Ferengi)

Zek was the Grand Nagus of the Ferengi Alliance throughout most of the timeine. In the First War, he suddenly announced his new successor, Quark (rather than his son Krax), and apparently died soon after. It was discovered that this was only a ploy to test his son's worthiness for the position. However, Krax did not succeed as expected, and Zek postponed his retirement.
